Juan Martin del Potro eliminated Andy Roddick in four sets this afternoon, commencing Roddick's retirement but prompting an emotional speech that suggested the American might be open to returning to competition in the future.

Roddick found himself on the wrong end of points throughout the 6-7 (1), 7-6 (4), 6-2, 6-4 match that was moved across days and courts due to bad weather in New York. But the spark he showed in seizing the first set (and nearly taking the second) may have led him to rethink hanging up the racquet forever. (Though, seriously, most people who retire have second thoughts.)

Regardless, we'll all debate exactly what Roddick meant by "hopefully I'll come back to this place someday and see all of you again," because it's vague and he's probably just trying to be nice. But seriously, indulge us, right? We can appreciate that tiny crack Roddick left in the doorway that is his career. [ESPN]
